Three teenage boys and a man have been charged with allegedly drugging and raping a young woman, then leaving her in a southern Sydney street three months ago.

On a Saturday night in October, it's alleged the 18-year-old woman met a 17-year-old boy known to her at a Lugarno pizza shop, with the pair then meeting up with friends of the boy - another 17-year-old , a 15-year-old and a man, 38.

It's alleged the woman was given an unknown substance and while under the influence, was sexually assaulted several times out the back of the shop.
